What is bad, > however, is that Abovenet still advertise the prefix surrending hosts they > block, blackholing these hosts for their BGP mutilhomed customers - this is pretty hard for abovenet to fix, since no router i'm aware of is able to take in a /13 from some customer, blackhole a smattering of /32's inside of it, and only send the remnants of the /13 to its downstreams. what MIBH does, as a transit customer of abovenet among others, is to take an RBL BGP feed just for the purpose of route-mapping all of its contents toward one of our other transit providers. (MIBH is the transit provider for MAPS, among other things, and MAPS has web servers which *must* be able to be reached by people listed on its RBL. is that funny, or what?) i agree that this is painful, and if it were my network i'd find some way to let abovenet's multihomed customers automatically avoid abovenet for things which aren't going to work.
